BOLL nx rneotron.

Application filed June 14, 1926. Serial mi. 115,902.

The present invention relates to a machine especia ly designed for separating and clean-' ton, to the end that the burr containing the cottonwill again be passed to the brushes and saws of the machine.

ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure l is a longitudinal sectional view through a machine constructed in accordance with the present invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a fragmental elevational view of one side of the machine.

Referring to the drawings in detail, the machine includes a housing indicated generally by the reference character 5, in which 35 housing the various brushes, saws and feed rolls are mounted for operation.

At the upper end of the housing 5 is an opening 6 through which the bolls that are treated by the machine, pass, on their ontrance to the machine.

The reference character 7 indicates feeding rolls which are geared to rotate slowly in opposite directions, to the end that the material fed into the machine will be passed downwardly to the rotary brush 8 that operates between the rolls 7 and in spaced relation therewith as shown by Figure 1, so that the bolls will be partially broken by their contact with the brush 8.

A casing indicated at 9 forms a part of the housing and is formed preferably of wire mesh material to the end that the brushes 10 of the member 8 will further act to break the bolls when they are rubbed against the casing therein. The housing 5 is constructed in such a way that there is provided an upper compartment 5' and a lower compartment 6, the compartn'ients communicating through the spout ll to the end that as the material is fed into the machine and carried over the casing 9 by the brush 8, the material will be thrown into the spout 11 and fed to the gin saw supported therein. The reference character'26 indicates a partitioning member dividing the housing into upper and lower comoarti'nents.

Operating adjacent to the spoutll is a feed brush 12which is designed to carry material to the gin saws 13 which inturn act to remove the lint cotton therefrom. As

shown by Figure 1, a roll 1a is provided, the same carrying substantially wide blades 15 that move in proximity to the brush 12, so that should bolls be fed laterally before the cotton is freed therefrom, the blades will catch the bolls and return them to the feed brush 12 to again be treated by the saws operating adjacent thereto.

- Operating at the same rateof speed as the feed brush 12 is a spike roll 16 which operates adjacent to the plate 17 to crush the bolls, the plate 17 also cooperating with the gin saws 13 to further crush the bolls. The bolls are removed from the gin saws by means of the brush 18 that contacts with the gin saws, the direction of rotation of the brush 18 being such as to throw the burrs into the discharge spout 19.

Cotton is removed from the gin saws by means of the brush 20 which operates in the casing 21 that in turn is provided with adischarge spout 22.

It might be further stated that adjustable spiked bars 22 are arranged adjacent to the front wall of the machine, the spiked bars 22 having arms extending'therefrom, which arms are connected by the bar 24 so that the bars 22 may be adjusted simultaneously. A lever 25 is provided for moving the bar 24 to accomplish this adjustment. The spikes thereof cooperating with the spikes of the ISO rolls 16 to break the bolls and due to the construction of the spiked bars 22, it will be seen that the spiked bars may be adjusted for treating bolls of various sizes and in various conditions.

From the foregoing it will be seen that the construction of the rolls and brushes of the machine are such as to thoroughly separate the burrs from the lint cotton, eliminating any possibility of the burrs passing through the machine with the lint cotton and thereby llt) causing a finer grade of cotton to be removed from the bolls.

I claim:

1. In a machine of the class described, a housing including an upper compartment and a lower compartment, gin saws operating in the lower compartment, a feed brush" for feeding material to the gin saws, a spiked roller operating achacentto the gin saws, a

' crushing plate disposed between the spiked roller and gin saws and adapted to cooperate With the spiked roller and gin saws to crush l'iollspassed into the machine, spikedbars cooperating with the spiked roller to break the bolls, and means for ad usting the spiked bars. I I

2. In a machine of the class described, a housing, a partitiemng member withln the housing and dividing the housing into communicating upper and lower compartments, gin saws operating adjacent to the partitioning member and disposed Within the lower compartment, a roll having a plurality of substantially Wide blades extending therefrom operating adjacent to the gin saws, a

plate disposed in spaced relation with the gin saws and against Which bolls move in passing through the machine to crush the bolls, and means for cleaning the saws.

3. In a machine of the class described, a housing, a partitionlngmember Within the housing for dividing the housing into communicating upper and lower compartments, gm saws operating in the lower compartinent, discharge spouts arranged on opposite ture, I JOHN VJOOLDRIDGE.
